Trim the ends off the king oyster mushrooms, soak them in salted water, then slice as desired. Cut the napa cabbage into bite-sized pieces and rinse in diluted salt water.

Heat a little oil in a pan, sauté minced garlic until fragrant, then add the mushrooms. Season with a little salt and a pinch of sugar. Add the cabbage and stir well. Once both are cooked, adjust seasoning to taste and add green onions before turning off the heat.

Transfer the stir-fried napa cabbage to a plate, sprinkle with black pepper, and serve with soy sauce and chili on the side.
